RESUMO
OBJECTIVES: Healthy individuals have significant beat-to-beat variability in heart rate, and this variability decreases with mental stress. We aim to use heart rate variability (HRV) to objectively compare mental stress levels in otologic surgeons at rest and during key portions of procedures. DESIGN: Pilot study. SETTING: Operating room and laboratory. PARTICIPANTS: Two neurotology fellows performed six mastoidectomy and facial nerve (FN) dissections in the operating room and six in a cadaver lab while continuous electrocardiograms were measured wirelessly. Five-minute samples were recorded during resting, preoperative, mastoidectomy, and FN dissection. Beat-to-beat time intervals were analyzed in time and frequency domains. The standard deviation of normal beat-to-beat intervals (SDNN) and the ratio of low frequency to high frequency power (LF/HF, measure of sympathetic tone) were calculated. Decreases in SDNN and increases in LF/HF indicate elevated mental stress. RESULTS: Mean resting SDNN was 43.9â±â9.2âms, not statistically different from preoperative SDNN (34.1â±â8.2âms, pâ=â0.13). SDNN decreased during mastoidectomy (29.4â±â11.7âms) and FN dissection (22.8â±â3.1âms), which was significant compared to preoperative values (pâ=â0.03). Intraoperative LF/HF increased for FN dissection (6.8â±â2.6) compared to resting (2.2â±â0.7, pâ=â0.004), indicating increased sympathetic tone. Mastoid and FN cadaveric procedures resulted in SDNN of 33.6â±â3.8 and 32.9â±â4.7âms, respectively, not statistically different from preoperative values (pâ=â0.82 and pâ=â0.94, respectively). Cadaveric FN dissection did not result in increased LF/HF (2.4â±â0.9) compared to resting (pâ=â0.94). CONCLUSIONS: Decreased HRV and increased sympathetic tone were observed intraoperatively, indicating high levels of mental stress, particularly with FN dissection. Similar changes were not found during cadaveric dissections.

OBJECTIVE: To describe and compare trends in prevalence, sexual behaviour and HIV transmission knowledge data related to sexually transmitted infections (STI) and HIV in patients attending three STI clinics over an 8-year period in Escuintla Department, Guatemala. METHODS: STI clinic attendees were classified into transmission groups as follows: female sex workers (FSW), men who have sex with men (MSM) and 'high-risk heterosexuals' (HRH). Annual cross-sectional analysis and multivariable Poisson regression adjusted for sociodemographic variables were used for prevalence comparisons and adjusted prevalence trends for HIV/STI outcomes and used for adjusted trends in proportions in sexual behaviour and HIV transmission knowledge outcomes. Endocervical swabs were obtained to detect trichomonas, chlamydia and neisseria infections. Serologies for syphilis and HIV were performed using rapid tests. For reactive HIV samples, positivity was confirmed by an ELISA. All reactive syphilis samples were further confirmed for diagnosis of active syphilis disease. RESULTS: From a total of 4027 clinic attendees, 3213 (79.78%) were FSW, 229 (5.69%) were MSM and 585 (14.53%) were HRH. The proportion of FSW, MSM and HRH who had a single visit was 56.42%, 57.23% and 91.10%, respectively. Overall, HIV prevalence was 2.10% in FSW, 8.17% in MSM and 4.12% in HRH. Prevalence trends in HIV and syphilis decreased in FSW. Prevalence trends in gonorrhoea did not decrease over time neither in FSW nor in HRH. Chlamydia and trichomonas infections in HRH showed an increase prevalence trend. In FSW, trends in condom use in last sexual intercourse with regular and occasional clients were above 93%. CONCLUSIONS: FSW show a decreasing trend in HIV, syphilis and chlamydia prevalence. Gonorrhoea prevalence in FSW and HRH did not decrease over time. HRH is a hard to engage population with low follow-up rates and high potential to act as a bridge population.

Objective: to assess the risk of falls in elderly, by comparing the sociodemographic and cognitive factors, history of falls and self-reported comorbidities. Method: cross-sectional and quantitative study with 240 elderly. Data were collected based on the social profile, through the instrument of risk of falls and assessment of falls, by univariate analysis, bivariate and multiple logistic regression. The Statistical Package for the Social Sciences (SPSS) version 19 was used for statistical analysis. Results: there was a significant association of the risk of falls, as measured by the Fall Risk Score, with sex (<0.001), age (0.054), cognitive status (<0.001) and history of falls (<0.001). All variables were statistically significant and contributed to the occurrence of falls. In logistic regression, the variables that showed association with risk of falls were: fall, with whom they live, hypertension and visual impairment. Conclusion: female gender, older elderly (over 80 years old), with low cognitive status and occurrence of previous falls in the last six months are factors that increase the prevalence of falls. In logistic regression, the variables that were associated with risk of falls were: fall, with whom they live, visual impairment and rheumatologic diseases.

Mother-to-child-transmission of HIV, syphilis, and hepatitis B virus (HBV) remains a challenge in Guatemala, especially in rural regions. A triple antenatal screening program for these infections using point-of-care (POC) testing offered through outreach teams was implemented in the municipality of Puerto de San José. One year following program implementation, antenatal care coverage increased to 99.6% (32.5% increase, P<0.001), testing uptake increased to 50.3% for HIV and syphilis (143.9% (P<0.001) and 1.3% (P=0.89) increase, respectively), and HBV testing increased from 0 to 42.2%. Lessons learned showed that, despite the expansion of triple antenatal POC screening in rural Guatemala, a shortage of healthcare workers and poor supply chain management limited screening uptake. Moreover, training is essential to help health workers overcome their fear of communicating positive results and improve partner notification. Engagement of community health workers was essential to build local capacity and facilitate community acceptance.

The world population is aging rapidly, which poses a greater challenge for the institutions involved which, in turn, require new public health policies that include the prevention of falls. The objective of this study was to assess the risk of falls in the elderly. This epidemiological, cross-sectional study was performed at a family health unit, using a quantitative approach. The sample consisted of 150 elderly individuals evaluated from January to April 2009. Data were collected using the Fall Risk Score, which was analyzed using SPSS 17.0. Of all seniors evaluated, 58.8% did not suffer falls. However, 63 seniors did suffer falls, 71.4% of this total experienced 1 to 2 falls, and the main intrinsic cause they reported was dizziness/vertigo, whereas the extrinsic cause was wet or slippery floors. Therefore, it is concluded that it is important to assess the risk of falls among the elderly so that preventive measures can be taken, with a view to maximizing their quality of life.

A população mundial vem envelhecendo de forma abrupta, o que representa um grande desafio para os órgãos competentes que, por sua vez, necessitam de novas políticas públicas de saúde, inclusive na prevenção de quedas. Este estudo objetivou avaliar o risco de quedas em idosos. Trata-se de um estudo epidemiológico de corte transversal com abordagem quantitativa, realizado em uma unidade de saúde da família. A amostra foi composta por 150 idosos avaliados de janeiro a abril de 2009. Para a coleta de dados, utilizou-se o Fall Risk Score, que foi analisado através do SPSS 17.0. Dos idosos avaliados 58,8% não sofreram quedas, sendo que, dos idosos que caíram (63 idosos), 71,4% sofreram de 1 a 2 quedas, citando como principal causa intrínseca a tontura/vertigem, enquanto que a extrínseca foi pisos escorregadios ou molhados. Conclui-se, portanto, que é de grande relevância avaliar o risco de quedas em idosos, para que se medidas preventivas sejam tomadas, com o objetivo de maximizar a qualidade de vida.

INTRODUCTION: Promoting screening for hypertension, high cholesterol, diabetes, and dental disease, particularly among residents of public housing, is a key strategy for achieving the objectives of Healthy People 2010. This community-based participatory research study tested a resident health advocate (RHA) intervention in public housing to increase use of mobile screening and to assess postscreening follow-up care for people with positive screening results. METHODS: During the summers of 2007 and 2008, a mobile health unit screened residents at 4 housing developments for hypertension, high cholesterol, diabetes risk, and dental disease. In the first summer, at 2 intervention sites, RHAs used personal contacts and repeated flyers to recruit residents; 2 control sites received standard recruitment, which was to leave flyers with the development manager. In the second summer, the 2 control sites from the previous year became intervention sites. For both summers combined, we calculated the number of people at intervention and control sites who used the van and we examined rates of appointments made and kept for residents who had positive screening test results. RESULTS: Screening rates were higher in the intervention condition compared with the control condition (relative risk [RR], 1.55; 95% confidence interval [CI], 1.12-2.15). Approximately 65% of participants screened positive for at least 1 condition. The proportion of participants with screen-positive findings who had follow-up appointments increased from 15% in 2007 to 55% in 2008. CONCLUSION: The use of RHAs increased participation in health screening among public housing residents and rates of follow-up medical visits for people with positive screening results.

Através de uma revisão integrativa da literatura, propõe-se analisar as características e particularidades das publicações envolvendo a Teoria das Representações Sociais no âmbito do envelhecimento. Método: Após análise das publicações do período de 2003 à 2009, a amostra final foi constituída de 23 das publicações, 11 na base de dados Scielo e 12 na Lilacs. Resultados: Observou-se a ausência de informações relevantes para que os estudos pudessem ser desenvolvidos, dentre estas podemos citar: a não especificação da formação do autor, do local e tipo de estudo e da abordagem empregada, bem como, a escassez de publicações de algumas temáticas como da visão que os idosos têm do cuidado a eles dispensado. Conclusão: Propõe-se que novos estudos sejam desenvolvidos para avaliar o envelhecimento sob a própria percepção daquele que o vive - o idoso- bem como a especificação de autoria e uma maior riqueza de procedimentos metodológicos.
